Touch Board - Development board for Electric Paint - Bare Conductive

Digispark is a development board based on the ATTINY85 microcontroller from ATMEL born in a successful campaign on Kickstarter.
Similar to the Arduino line , It is one of the smallest boards on the market.
Programmable directly from USB with the same Arduino tools. It has a built-in Micronucleus bootloader and can be replaced by similar ones such as the Trinket bootloader. Adafruit or others.
You can use many of the same Arduino libraries and you have your own on the digispark wiki. Arduino compatible Attiny85 Digispark board features:
- USB power supply
- External power supply (7v-35v DC 12v maximum recommended)
- 5V DC 500mA regulator on board
- Programmable with the Arduino IDE
- Loaded with Micronucleus bootloader

The Spartan Edge Accelerator Board is an FPGA board developed by Xilinx Spartan in the form of a Shield for the Arduino UNO board. In addition, the integrated ESP32 chip also provides WiFi and Bluetooth functionality.

FinestraMiner is a highly efficient Helium compatible hotspot that provides wireless network coverage to the Helium network, also called People's Network, the world's largest and fastest growing LoRaWAN network. It allows thousands of IoT devices to connect to this single hotspot using Long-Fi technology, with long-range coverage up to 16 kilometres away.

The Helium network is a decentralised wireless network that allows devices anywhere in the world to connect to the Internet wirelessly.

This Seeeduino XIAO is the smallest board in the Arduino-compatible Seeeduino family. It is an Arduino microcontroller, integrated with the ESP32-C3 RISC-V microchip. Despite its tiny size, it has enough interfaces for a multitude of applications. MCU board with Wi-Fi and Bluetooth 5.0, supported battery charging, energy efficiency and rich interface.

The Spectrum Digital XDS100v2 is the second generation of the XDS100 family of debug probes (emulators) for IT processors.
The XDS100 family presents the lowest cost of the entire XDS family of debug probes while supporting the traditional JTAG standard (IEEE1149.1).
In addition, all XDS debug probes support Core and System Trace on all ARM and DSP processors that have an Embedded Trace Buffer (ETB). The Spectrum Digital XDS100v2 connects to the target board via a 14-pin TI connector and to the computer via high-speed USB 2.0 (480 Mbps).
It also requires a license of Code Composer Studio „¢ IDE running on the computer.
Support for Code Composer Studio V4 (Does not support Code Composer Studio V3.3). XDS100V2 Emulator DSP/ARM CCS4/5/6 XP/ WIN7/8/>
